Furnace Replacement Cost Breakdown (2026)
Here is where the money actually goes on a Sandy Springs furnace replacement. These are line-item ranges pulled from real jobs we have quoted and installed across Sandy Springs, Dunwoody, Roswell, and the surrounding north Fulton County market in 2026.
| Cost Component | Typical Range (Sandy Springs) | Notes |
|---|---|---|
| Furnace unit (80% AFUE, mid-efficiency) | $1,800 – $3,200 | Goodman, Rheem, or Lennox entry-level |
| Furnace unit (96% AFUE, high-efficiency) | $2,500 – $4,500 | Carrier, Trane, Lennox, Bryant |
| Furnace unit (modulating/communicating, 97-98% AFUE) | $4,000 – $7,000 | Top-tier units for larger Sandy Springs homes |
| Labor and installation | $1,200 – $2,800 | Includes removal of old unit, sheet metal, venting adjustments |
| Permit (City of Sandy Springs) | $85 – $250 | Mechanical permit required; based on scope |
| Ductwork repair or modification | $400 – $1,500 | Often needed on older homes in the Riverside Drive and Huntcliff areas |
| Thermostat replacement | $150 – $400 | Smart thermostats on the higher end |
| Gas line modification | $200 – $600 | Only if the new unit has different gas supply requirements |
| Electrical work | $150 – $500 | Disconnect, wiring updates for high-efficiency blowers |
| Old unit disposal | $75 – $150 | Removal and recycling of the old furnace |
Here is the thing about those numbers: what you actually pay depends on whether you’re replacing like-for-like or upgrading. If your current furnace is an 80% AFUE single-stage and you are swapping in the same efficiency level, you will sit near the bottom of the range. If you decide to move from an 80% unit to a 96% two-stage, you are looking at a different job entirely. The unit costs more, the flue pipe often changes from metal to PVC, and the condensate drain needs to be added. That is the difference between a $4,800 job and a $7,500 job on the same house.
We replace furnaces from all nine major brands we’re factory-trained on: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. What that means for you is straightforward: we do not push one brand because we get a spiff on it. We match the unit to your house, your ductwork, and your budget. And before any work begins, you get a written price. Not an estimate range. The price.
What Affects Furnace Replacement Pricing in Sandy Springs
Some pricing factors are universal. A few are specific to Sandy Springs. Here is what moves the number up or down.
- Home age and construction era. Sandy Springs has a wide spread of housing stock. Homes built in the 1950s and 60s in neighborhoods like North Springs and Windsor Heights often have tighter mechanical closets, smaller return drops, and old asbestos-wrapped ducting that can complicate a replacement. Homes built in the 1990s and later in areas like the Chattahoochee River corridor typically have modern HVAC framing and cost less to work on.
- Furnace efficiency tier. An 80% AFUE unit is the cheapest to buy and install. A 96% unit costs more but qualifies for utility rebates from Georgia Power and City of Sandy Springs natural gas service provider rebate programs that can knock $300 – $600 off the effective price. A modulating unit with variable-speed blower will be $2,000 – $4,000 more than a basic single-stage.
- Ductwork condition. This is the one most homeowners do not plan for. A 2,200-square-foot mid-century ranch with original ducting may need $800 – $1,500 in duct sealing, replacement boots, or plenum work before the new furnace will operate correctly. We flag this during the estimate visit and put it in writing, so it is not a surprise line item later.
- Permit and inspection requirements. The City of Sandy Springs requires a mechanical permit for furnace replacement. The fee is $85 – $250 depending on the value of the work and whether we are altering gas lines or electrical circuits. We handle the permit. The inspection is scheduled after the job, and Sandy Springs inspectors are thorough. Jobs in Sandy Springs proper take one business day longer on average than jobs in unincorporated Fulton County because of inspection scheduling.
- Crawl space vs. basement vs. attic. A furnace in an open basement or garage is the fastest and least expensive install. A furnace in a crawl space or a low-clearance attic (common in the split-level and tri-level homes near Abernathy Greenway and Johnson Ferry Road) adds $300 – $700 in labor because of access difficulty and safety rigging requirements. If the tech has to haul the old unit and the new unit through a tight attic hatch, that is extra time and extra care.
- Time of year. Sandy Springs winters are cold enough that our busy season runs November through February. Replacing a furnace in December, when your heat is down, typically costs 10 – 15% more than a planned replacement in March or April. Some of that is material price fluctuation. Most of it is labor demand. If your furnace still runs, scheduling the replacement in spring or fall saves real money.
Furnace Replacement Cost by Home Size in Sandy Springs
The size of the furnace (measured in BTUs) is sized to your home’s square footage, ceiling height, insulation, and window load. Here is what that looks like in dollars for typical Sandy Springs homes in 2026.
- Condo or small home (up to 1,400 sq ft): 40,000 – 60,000 BTU furnace. Replacement cost: $3,800 – $5,500 depending on efficiency.
- Mid-size home (1,400 – 2,400 sq ft): 60,000 – 80,000 BTU furnace. Replacement cost: $4,500 – $7,200.
- Large home (2,400 – 3,500 sq ft): 80,000 – 100,000 BTU furnace. Replacement cost: $5,800 – $9,500.
- Very large or custom home (3,500+ sq ft): 100,000 – 120,000+ BTU furnace, often with zoning. Replacement cost: $8,500 – $14,000.
Sandy Springs has a lot of homes in the 1,800 to 2,600 square foot range, which is exactly where the average $5,000 to $6,500 replacement price comes from. If you are in a 2,400-square-foot home off Spalding Drive and want a 96% efficient two-stage furnace with a variable-speed blower, expect to be quoted in the $7,000 – $8,500 range with quality installation included.
How to Save on Furnace Replacement
You are not going to find a cheap furnace replacement in Sandy Springs, and you should not want one. What you can do is pay a fair price for a correctly installed unit and avoid the mistakes that cost you money later. Here is how.
Time the replacement for off-peak season
Schedule between March and September. You will get more scheduling flexibility, and some manufacturers run spring and fall promotions on equipment. In Sandy Springs, the window between late February and mid-October is ideal. You avoid the December emergency replacement that costs more and forces faster decisions.
Get the efficiency right, not just high
A 96% furnace saves money on gas over an 80% unit, but the payback period matters. For a Sandy Springs home with mild winters and natural gas rates averaging around $1.40 per therm, the annual savings of a 96% over an 80% unit is typically $150 – $250 per year. On a $2,000 price difference, that is an 8- to 13-year payback. If you plan to stay in the home 10+ years, it is worth it. If you are selling in three years, a mid-efficiency unit with a good warranty is the smarter spend.
Check for manufacturer and utility rebates
Carrier, Trane, and Lennox run rebates in the spring and early fall, usually $100 – $600 depending on the unit. Natural gas utilities serving Sandy Springs also offer efficiency rebates. We track what is current when we quote and list the rebate on the written proposal, so you know the net cost before you sign anything.
Ask about the warranty terms, not just the length
A 10-year parts warranty is common on most brands. What separates quality installers is the labor and workmanship coverage. Every Dalton Heating & Air Sandy Springs replacement includes our written guarantee, and if the repair fails within the guarantee period, we return at no charge. That is the 365-Day Done Right Promise, and it is in writing on every job we do. The equipment warranty protects the parts. Our promise protects the whole result.
Never skip the permit
Some contractors will offer to replace a furnace without pulling a City of Sandy Springs permit. That looks like a $200 savings. It is not. Unpermitted HVAC work can cause problems when you sell the house, and it represents a shortcut on the very part of the job that protects against carbon monoxide risks. We pull a permit on every furnace replacement in Sandy Springs. No exceptions.

Furnace Replacement vs. Furnace Repair: Which Makes More Sense?
This is the question every Sandy Springs homeowner faces when the furnace starts acting up. The short answer: if the repair costs less than half the replacement price and the unit is under 10 years old, repair it. If the unit is 15+ years old or the repair involves a failed heat exchanger, replace it.
Furnace repair in Sandy Springs runs $150 – $700 depending on the part. Common repair jobs like a failed ignitor, bad pressure switch, or a failing blower motor capacitor cost $180 – $400. A cracked heat exchanger is a different situation. It is a safety issue that requires a special red-tag procedure, and replacement of the heat exchanger alone can run $900 – $1,800 on a furnace that may be 80% through its service life anyway. At that point, a full replacement is usually the financially responsible path.
Here is a useful rule of thumb we give homeowners in Dunwoody and Sandy Springs: take the repair quote, multiply it by the age of the furnace. If that number exceeds the replacement price, replace the furnace. A $350 repair on a 4-year-old furnace is a no-brainer repair. A $600 repair on a 16-year-old furnace puts you at $9,600, which is well past the replacement threshold.
How the Furnace Replacement Process Works
Here is what we do on a typical Sandy Springs furnace replacement from start to finish. This is the same process whether your home is in Huntcliff, the Perimeter Center area, or a neighborhood off Johnson Ferry Road. We follow The Garrison Code on every job: arrive inside the stated window, price in writing before starting, do the job by the book, leave the site clean, and stand behind the work for a full year.
- Call us at (478) 400-5908. A real person answers, 24/7. Not a voicemail queue. You tell us what is going on and schedule an estimate at a time that works for you.
- Technician visits your home. We inspect the existing furnace, measure the ductwork, check the gas line, and assess access. We talk to you about your heating needs, comfort complaints, and budget. This visit takes 45 – 90 minutes depending on your house.
- You get a written proposal. The price is in writing before any work begins. It lists equipment options, efficiency levels, labor, permit, and the warranty terms. You compare options and decide. No pressure. No price changes at the door.
- Installation day. A background-checked, uniformed crew arrives inside the scheduled window. We remove the old furnace, install the new unit, connect gas lines, test for leaks, verify airflow, and clean the work area. Most replacements take 4 – 8 hours.
- Sandy Springs inspection. We schedule and attend the city inspection. If the inspector flags anything, we correct it immediately and at no additional charge.
- Walkthrough and your written guarantee. We show you the finished job, explain the thermostat, and hand you the written warranty. Your 365-Day Done Right Promise is active the day the job finishes. If anything is not done right, we make it right.
Why Furnace Replacement Costs in Sandy Springs Differ from Other Markets
If you compare quotes from Sandy Springs to quotes from Cobb County or south Fulton County, you may notice a difference. That is not arbitrary. It is driven by local factors.
The City of Sandy Springs has its own mechanical permitting and inspection process that is more involved than some surrounding jurisdictions. Inspector availability affects scheduling, and that adds a real but reasonable cost. Homes here also skew larger and older than the metro average, which means more furnaces being replaced are in crawl spaces, attics, or tight mechanical closets built before modern HVAC clearances were standard. Materials and equipment pricing is the same as the rest of metro Atlanta, but the labor reality is different: a furnace replacement in a 1962 ranch on a crawl space takes more time and more care than a swap-out in a newer garage closet.
We are a home service company that works in Sandy Springs every day. Our pricing reflects the actual conditions of the houses here, not a calculator from a national franchise. Marco Benitez, who leads Dalton Heating & Air Sandy Springs, has seen enough of these homes to know when a quote is realistic and when it is a guess. That is why our Furnace Replacement in Sandy Springs service includes a detailed written price on every job, with no number pulled out of the air.
FAQs – Furnace Replacement Cost
How much does a furnace replacement cost in Sandy Springs in 2026?
Most furnace replacements in Sandy Springs cost between $4,200 and $8,900, with the typical job landing between $5,000 and $6,500 for a mid-efficiency unit with installation, permit, and removal included. High-efficiency replacements run $7,000 to $12,000 depending on home size. Call (478) 400-5908 for a free written estimate based on your specific home.
How long does a furnace replacement take?
Most single-unit furnace replacements take 4 to 8 hours of on-site work, and the entire process from estimate to final inspection takes 5 to 10 business days in Sandy Springs, depending on city inspection scheduling. Same-week installation is common when you call outside the November-to-February busy season.
Is it cheaper to repair or replace a furnace?
Repairs in Sandy Springs run $150 to $700, while replacement runs $4,200 to $8,900. If your furnace is under 10 years old and the repair is under $400, repair it. If the unit is 15+ years old or has a failed heat exchanger, replacement is the better financial choice. A technician can give you a straight answer after a diagnostic visit.
What size furnace do I need for my Sandy Springs home?
A 1,400-square-foot home typically needs a 40,000 to 60,000 BTU furnace. A 2,400-square-foot home needs 60,000 to 80,000 BTUs. Larger homes need 100,000 BTUs or more. We calculate the load based on your home’s insulation, windows, and ceiling height, not just square footage. Getting this wrong causes short cycling, high bills, and uneven heat.
Can you replace my furnace the same day I call?
We can often install a replacement within 24 to 48 hours of your estimate, but a same-day furnace replacement requires that the unit is in stock and the city permit is available. During peak winter months, 2 to 5 days is more typical. If you have no heat and it is an emergency, call (478) 400-5908 and we will get you on the schedule as fast as physically possible.
Do I need a permit to replace a furnace in Sandy Springs?
Yes. A mechanical permit from the City of Sandy Springs is required for furnace replacement. The permit costs $85 to $250 and covers the required inspection. Dalton Heating & Air Sandy Springs pulls the permit on every job. We never offer to skip it, because a skipped permit can cause issues when you sell the house and represents a safety shortcut we will not take.
Will a new furnace lower my gas bill?
A 96% AFUE furnace uses about 16% less gas than an 80% unit, which translates to roughly $150 to $250 in annual savings for a typical Sandy Springs home at current natural gas rates. The savings are bigger in cold winters and if your current furnace is operating below its rated efficiency. We can estimate the payback on your specific replacement when we quote it.
